Jai Sri Vamana Bhagwan,
Sri Sri Vamana avatar is one among the 10 main incarnation of lord Sri Hari Vishnu,
Aditi, the mother of Great Sun, who by nature pious and alike great saintly soul requested Lord Sri Hari vishnu to incarnate in form that tie the then king Bali, grandson of great devotee of Lord Sri Hari vishnu known in the name of Prahlad,
Indra was deprived of his heavenly kingdom and Bali was the cause and he requested Mother Aditi for favor from Lord Sri Hari Vishnu,
Lord Sri Hari vishnu incarnated as Dwart, a young brahmana, who approached bali who was known for his munificence for a gift of land which could covered by his three steps for the cause, Bali awarded without even a fraction of thought to that brahman,
Lord covered the earth and the all regions including supreme heaven and for third bali submit his head being the man of words, lord ask him to go to netherworld and lord becomes the Trivikram who encompassed the inverse with his two steps,
Lord Sri hari vishnu is beyond perception of faculty of man, the one who had to resort to the dwarfs form while begging, is true brahman versed with skill to cover the universe through the power of his spirit and he respect his devotees all the way and aditi was his devotee,
Vishnu Vishnu Vishnu
